Well, after their terrible treatment of deuterium in "Demon" the Voyager writers learned their lesson and talked about it sensibly in "The Void". Now they're back to abusing it again. For the record; deuterium is a type of Hydrogen. You can scoop it directly out of space itself - that's just what the glowing red things on the front of Starship nacelles are for. If you want easy access to large amounts you can scoop it out of a gas giant atmosphere, or get it from the ice of a Europa-like moon or a comet. In other words there is plenty of the stuff drifting around out there, entirely free for the taking. Under Earth-like conditions it is a very light gas, much like ordinary Hydrogen. So you can't mine "strata" of it from under the ground like it was coal or oil. And even if you could, it's not exactly going to be terribly valuable.

When T'Pol pulled all her fancy Vulcan karate, I couldn't help but wonder why she didn't simply neck-pinch the Klingon? It would have been much quicker and more efficient, I think.

Did anybody else think the Klingons gave up far too easily? After being made to look like fools by the locals, the head of the colony demands that they leave and never come back - and they do! I was waiting for them to beam back down behind the defenders and open fire, or blast the camp from orbit.

Great Moment :

A new Klingon ship - although like most Enterprise ships it looks too futuristic for this time period, it is nice to see a new ship designs arriving for the Klingons.

Body Count :

Various fighting goes on, but nobody is killed.

Factoid :

Larry Cedar, who played "Tessic" in this episode, also played "Tersa" in Voyager's "Alliances" and "Nydrom" in DS9's "Armageddon Game".

Plotline

Enterprise's crew visits a Deuterium mining camp to buy some fuel for the ship. When Archer finds that the miners are living under constant fear of attack from a group of rogue Klingons, he decides to stay and help them defend themselves.
